The NEC M402 supports a maximum resolution of 1920 x 1200 (WUXGA). That's over seven times the resolution of a 640 x 480 (VGA) projector, which is the most common resolution supported by 10000:1 contrast ratio projectors that have been available for a similar time to the M402. 640 x 480 (VGA) is also supported by this data projector. In addition, this multimedia projector support graphics resolutions of 1024 x 768 (XGA), 1280 x 1024 (SXGA), 1400 x 1050 (SXGA+) and 1600 x 1200 (UXGA) and 800 x 600 (SVGA).
A 1920 x 1200 (WUXGA) graphics resolution is in fact the best supported resolution across all projectors that have been on the market for around the same time as the M402.
The worst supported resolution across comparable types of projector is 640 x 480 (VGA).
